Andrew Bynum couldn’t say for sure when he might make his 2010-11 debut, but it probably won’t be until late November. The Lakers’ 7-foot center said today at media day that he faces four more weeks of inactivity after undergoing offseason surgery on his right knee. He also revealed that the July 28 surgery performed by New York-based doctor David Altchek involved a repair of the torn meniscus. More often, damaged cartilage is simply cut away, but Altchek mended Bynum’s meniscus in this case. In general, the operation requires a longer recovery time than the typical six to eight weeks.
